don't call setSize() when creating SurfaceControl

When SurfaceControl is created with creating variable
in updateSurface(), sizeChanged is also set.
So, setSize() is called, and it blocks UI thread
until the transaction is handled in SF.
There is no need to resize in the creation time,
because size is already set when creating SurfaceControl.

Test: systrace any app including SurfaceView
